Acrochordon

Acrochordons, or skin tags, are small benign tumors that form primarily in areas where the skin forms creases, such as the neck, armpits, and groin. They also occur on the face, usually on the eyelids. They range in size from two to five millimeters, although larger ones have been seen. The surface of acrochordons may be smooth or irregular in appearance. Often, they are raised from the surface of the skin on a fleshy stalk called a "peduncle."

Acrochordons are harmless, although they are sometimes irritated by clothing or jewelry. Why and how skin tags form is not entirely known, but there are correlations with age and obesity. They are more common in people with diabetes mellitus. It is estimated that by age 70, up to 59 percent of people have them. A genetic component (causation) is thought to exist.
